For truck owners and technicians, ensuring a tight and reliable seal in the engine’s exhaust system is critical for optimal performance and emissions control. This task demands the use of authentic and durable Foton truck parts. The 3697750 Exhaust Manifold Gasket is a genuine OEM component engineered to provide a perfect seal between the exhaust manifold and the cylinder head. Designed specifically for FOTON engines, this gasket, identified by the part number 3697750, prevents exhaust gas leaks, maintains backpressure, and protects engine components from heat damage.

The 3697750 is a specialized sealing component placed between the exhaust manifold and the cylinder head in FOTON truck engines. Its primary function is to create an airtight barrier that contains hot, high-pressure exhaust gases as they exit the engine cylinders and flow into the exhaust manifold. A proper seal is essential for maintaining engine efficiency, as leaks can lead to power loss, increased fuel consumption, and elevated emissions.
The 3697750 is constructed from high-temperature materials such as multi-layer steel or composite graphite, capable of withstanding continuous exposure to exhaust gases exceeding 1500°F (815°C). This prevents burnout and ensures a durable seal under severe operating conditions.
By preventing exhaust leaks, the 3697750 maintains correct exhaust backpressure, which is crucial for engine tuning and turbocharger efficiency. This leads to optimal combustion, full power output, and improved fuel economy, saving operational costs over time.
A secure seal ensured by the 3697750 prevents unburned hydrocarbons and other pollutants from escaping before reaching the catalytic converter. This helps your truck meet emission standards and reduces its environmental footprint.
Manufactured to exact FOTON specifications, the 3697750 gasket matches the bolt holes and port shapes of your engine perfectly. This eliminates guesswork during installation, reduces the risk of misalignment, and ensures a quick, hassle-free replacement.
The 3697750 Exhaust Manifold Gasket incorporates advanced engineering to handle the demanding environment of a diesel truck engine. It typically features a multi-layer steel (MLS) design with embossed sealing beads that concentrate clamping force for a superior seal. Some versions may use a flexible graphite core with stainless steel inserts for enhanced conformability to slightly uneven surfaces. The gasket is coated with a heat-resistant anti-stick material to prevent bonding to the manifold and cylinder head, facilitating easier future removal.

Installing the 3697750 correctly is vital for its performance and longevity. The engine must be completely cool before starting. Disconnect the battery and remove any components obstructing access to the exhaust manifold. Carefully unbolt the manifold, noting the sequence to prevent warping. Clean the mating surfaces on both the cylinder head and manifold thoroughly with a scraper and solvent to remove old gasket material and carbon deposits.
The 3697750 Exhaust Manifold Gasket is designed for a range of FOTON commercial trucks and buses equipped with specific diesel engines, such as those in the Foton Auman, Tunland, and Ollin series. It is a critical replacement part during engine overhauls, head gasket jobs, or when addressing exhaust leaks. Common symptoms indicating the need for a new 3697750 include a ticking or hissing noise from the engine bay, especially on acceleration, a smell of exhaust fumes near the engine, visible soot around the manifold area, loss of engine power, or increased fuel consumption. Using the genuine 3697750 ensures restoration of factory performance and reliability for these applications.
The 3697750 is engineered to endure the rigorous demands of commercial trucking. Daily thermal cycling—heating up to extreme temperatures and cooling down—can cause inferior gaskets to crack or lose their seal. The multi-layer design of the 3697750 accommodates this expansion and contraction without failing. Its materials resist corrosion from exhaust condensates and chemical exposure. In real-world use, trucks equipped with the genuine 3697750 gasket experience fewer unscheduled stops for exhaust repairs, maintain consistent power output, and have longer intervals between major engine services. For fleet operators, this translates into higher vehicle availability, lower maintenance costs, and improved total cost of ownership.
Choosing the authentic 3697750 over aftermarket alternatives is a decision that impacts engine health and operational safety. Counterfeit or low-quality gaskets may use substandard materials that degrade quickly, lack proper coatings, or have imprecise dimensions. This can lead to immediate leaks, overheating of adjacent components, or even exhaust gas entering the engine bay, posing a fire risk. The OEM 3697750 is tested and validated as part of the engine’s sealing system, ensuring it meets all thermal, pressure, and durability requirements. It also preserves any existing engine warranty. When the integrity of your engine’s exhaust seal is at stake, the genuine 3697750 offers guaranteed performance and peace of mind.
Regular inspection of the exhaust system can help identify when the 3697750 gasket might be failing. Listen for unusual exhaust leaks, which often sound like a tapping or blowing noise that increases with engine RPM. Visually check around the manifold-cylinder head junction for black soot stains, which indicate escaping gases. Monitor engine performance metrics; a sudden drop in power or fuel efficiency can signal a leak. During routine service, if the exhaust manifold is removed for any reason, always replace the 3697750 gasket with a new one—reusing old exhaust gaskets is not recommended. Keeping the exhaust system clean from excessive carbon buildup can also help extend the life of the gasket by promoting more even heat distribution.
The 3697750 Exhaust Manifold Gasket is an indispensable component for maintaining the performance, efficiency, and environmental compliance of your FOTON truck engine. Its robust design and precision engineering ensure a reliable seal under the most demanding conditions, protecting your investment and minimizing downtime. By selecting the genuine OEM part identified as 3697750, you guarantee a perfect fit, superior materials, and performance that meets the original design specifications. Whether you are performing preventative maintenance or addressing a specific leak, installing the 3697750 is a smart choice for optimal engine operation and long-term reliability in your commercial vehicle.
